Sorry for bringing up an old topic but I recently decided to start playing FO3 again and just like most others in this topic I too began suffering from the bigger left arm issue. And just like the others I'm using W7 64. I tried BoG's replacer however the arm issue is even worse there with the arm being HUGE and the hand being called a "man-hand" would be generous. The issue isn't as bad with dimons but the arm and hand are still bigger than they should be. Has anyone found a fix for this issue yet? It definitely seems to be a problem between FO3 and W7 as the problem did not exist for me on XP or Vista.
